According to the numbers given on Internet Adult Film Database profiles, the average female porn star weighs 117 pounds (53 kilograms), which is 48 pounds (22 kg) less than the average American woman. High obesity rates among the public may explain some of the discrepancy in breast size porn actresses are also thinner than the average American woman. In fact, the most common bra size among porn stars is a 34B, compared with 36C for the average American woman. The stereotypical porn actress - with enormous breasts and blonde hair - doesn't match reality, Millward found. Stereotypes were the motivation for Millward, whose analysis of porn stars includes a facial composite of the 'average' actress. Ultimately, the findings could lead to better understanding of sexual health, sexual identity and other aspects of the high-grossing porn business. Though it's hard to know for sure without more extensive studies, early explorations have found these stereotypes fail to hold up.
This lack of research is notable given the number of stereotypes about porn actresses, particularly that they have high rates of childhood sexual abuse and psychological problems.
